Additional checks in terraform plan

[marina-chibizova]

Currently /terraform plan may be successful but the resource still fails after the pull request merge with the error "Unable to validate configuration". It happened with the confluent_connector resource. Probably due to insufficient SA permissions but it was impossible to predict with the plan. More profound checks are needed on this stage to prevent infrastructural breakdowns due to resource failure.

@marina-chibizova we've just released a new version of TF Provider for Confluent (1.43.0) that includes a partial fix for this issue: we've added this check for confluent_schema resource.

Let us know if you're able to reproduce it when using the latest version of TF Provider!
